mobymac

Automagically install Docker in a VirtualBox VM with super-fast NFS mounts.

What does it do?

• Uninstall Docker for Mac
• Install Virtualbox
• Install docker client binaries
• Create a boot2docker VM
• Set up NFS mounts for VM
• Set up docker environment in .bash_profile, .zprofile or fish.config (optional!)

Installation (easy)

Use the latest docker version, 4GB RAM for the VM and set up .bash_profile:

curl -sfSL https://github.com/dziemba/mobymac/raw/master/install.sh |bash -s bash 4096

Installation (advanced, recommended)

# download installer
curl -sfSL https://github.com/dziemba/mobymac/raw/master/install.sh -o mobymac.sh
chmod +x mobymac.sh

# verify that it does what you want
less mobymac.sh

# run it
./mobymac.sh

# ... or run it with more params:
# ./mobymac.sh [shell integration] [VM memory in MB] [Docker version]
./mobymac.sh zsh
./mobymac.sh zsh 2048
./mobymac.sh zsh 2048 v17.06.0-ce

Shell integration can be one of the following: bash, zsh, fish or manual.

Notes

• Yes, the name mobymac is very confusing.
• This will destroy all your existing docker data, be careful!
• NFS mounts have less guarantees regarding FS consistency - in practise it should just work (tm)
• Ports are not mapped to localhost - run docker-machine ip to find out the docker VM IP

Why?

Docker for Mac is an awesome project - use it if you can. It is however still slower than this approach. Also there are some weird DNS issues that do not occur with a VBox solution. When Docker for Mac is stable enough, this project will become obsolete.
